This beautiful wallpaper shows North Cascades National Park Service Complex in Washington. Jagged peaks, deep valleys, cascading waterfalls and over 300 glaciers adorn the North Cascades National Park Service Complex. Three park units in this mountainous region are managed as one and include North Cascades National Park, Ross Lake, and Lake Chelan National Recreation Areas. These complementary protected lands are united by a contiguous overlay of Stephen Mather Wilderness.
